+## null和undefined明显的错误使用方式现在会报错
+
+例子：
+
+```TypeScript
+var ResultIsNumber17 = +(null + undefined);
+// Operator '+' cannot be applied to types 'undefined' and 'undefined'.
+
+var ResultIsNumber18 = +(null + null);
+// Operator '+' cannot be applied to types 'null' and 'null'.
+
+var ResultIsNumber19 = +(undefined + undefined);
+// Operator '+' cannot be applied to types 'undefined' and 'undefined'.
+```
+
+相似地，把null和undefined当做具有方法的对象使用时会报错。
+
+例子：
+
+```TypeScript
+null.toBAZ();
+
+undefined.toBAZ();
+```
